Abstract

A system and method of alternately purging an in-situ sensor with clean fluid and sampling a fluid volume of interest, in order to eliminate drifts and errors associated with the absorption of chemicals to the sensing elements of in-situ sensors. The system and method effectively processes the output of the in-situ sensor using this alternating sample and purge cycle to detect and identify chemicals accurately and reliably. The system and method also effectively reduce errors induced by temperature and humidity drifts in the ambient, and the sampled, fluid.
